new soKo ov, on BROOKLYN, NEW YORK, ASSIGNOR of ONE-HALF To JOHN matrix, or NEwYonK, N. Y. a y y flbnlltolwmtt may ooaoernsw l V "ienlll known that I, Jason SoKoLov, a citizen oil the United States, residlng at 2 Brooklyn, State of New York, have invented certain new and useful Improvements in. Wrenches, :of which the following is a specification. a a l y It is the object of my invention to provide a simple and effective construction of ratchet wrench permitting the wrench head to rotate in either direction by the handle by ratchet action or to be locked in fixed relation with respect to the handle. To thes-eends l have provided a construction of the character hereinafter described and i ll or an illustration of one or the forms my invention may take reference is to be had to the accompanying drawing, in which Figure 1 is a plan view of a wrench e1nbodying my invention. Fig. 2 is a vertical sectional view, on enlargedscale, taken on the line A' A of Fig. 1. Fig. is a perspective View of the locking means. Fig. 4; shows in plan viewthe wrench head with locking means, the handle and screw dismembered from each other. 1

.The wrench head H has formed thereon the one aw'member J, the other jaw Imemher J having :lformedthereon the member A movable longitudinally in a channel or groove in the head member H. The memher A has atits one edge the teeth T with which meshes the worm W supported in and rotatable with respect. to the head member H, rotation of the worm W causing move ment of jaw J with respect to jaw J to accommodate different sized nuts or bolts to be actuated by the wrench.

In the head H, with its axis at right angles or normal to the plane of movement of the head H is the cylindrical socket S having at its bottom the inturned flange or lip F. Movable vertically in the socket S, and rotatable therein, is the cylindrical member B within which is housed the spring C which rests at its lower end upon the flange F and thrusts upwardly upon the end of the cavity within the member 1%. Upon the member 13 is the horizontally disposed circular member I) having a plurality of depressions or other roughening means E for creating friction between the member I) and a thumb or finger for easily rotating the locking means.

and screwed home.

per face of the disk or ring D is thedetent ineniber G having the substantially parallel faces K and L, the upper sloping or inchned, face M and the substantially vertical iaceN. y

. The wrench handle 0 has at its one end a circular aperture P. througlrwhich ex tends the shouldered screw Q which engages in the head H by screw. threads R,

one side of the. shank of the screw Q, being flattened as at U, to allow. free rotation of themilled disk 11).: Around the aperture P in the handle 0 are the slots V of a width sliglitlygreater than the width of the detent lnemberGra.

In assembling the wrench, the shell B forcing the same downwardly, as viewedin Big; 2, and then. the nut Q, 1s introduced In so assembling the? parts, the member-1B may be depressed out i a Patented Aug. 25, 1914; 1 Application filed July 1, 1913. SerialNo. 776,748.

and spring 3 are introduced into the socket i t l I u b, then the handle member 0 1s placed in positlon on top of the detent member Gr,

dislrl). He may rotate the disk D so as to bring the detent member G into alinement with any ofthe slots V in the handle 0 in which case the spring C will raise the detent member G into the slot V, the faces K and; L. of thedetent member G in such. case lying parallel to the side faces of the slot V. such case the head H of the wrench-is locked in fixed position with respect to the handle 0, and force may be applied in either direction to the head H so that the wrench operates as if the head H were fixed to the handle 0.

To transform the wrench into a ratchet wrench, the operator rotates the disk D, after depressing the same in opposition to spring C .to withdraw detent member G from the slot V; and he may rotate it to a position substantiallyat right angles to the position above described in which case the top edge or portion X of the detent member G will extend into a slot V, being held therein by the spring 0 and will engage against one side of the slot V, in which case movement of the handle toward slots, and rides over them and in so doing depresses the detent member in' Opposition to spring C and as the detent member comes" into alinement with the successive slots it snaps up into the same so that the handle can be againrotated in the first named direction to give a further rotative movement to the head H. And by rotating the detent member G through one-half a revolution from the last named position the head H may be rotated by ratchetaction in opposite direction to that last described.

lVhat I claim is: 1. In a wrench, the combination with a head, of a detent member carried thereby and movable normally at right angles to the plane of movement of said' head, a

' handle pivotally mounted upon said head,

said handle having a plurality of grooves or slots adapted to receive said detent, and

means for depressing and rotating said detent, said detent member adapted to engage in said grooves or slots in three positions, whereby said handle may drive said head in either or both directions.

v 2. In a wrench, the combination with a wrench head, of a cylindrical socket therein, a hollow cylindrical shell adapted to move longitudinally in said socket at right angles to the plane of movement of the wrench head and to rotate in said socket, a handle pivoted to said head, said handle having a plurality of grooves or slots, and a member carried by said shell and adapted to engage in said grooves or slots.

8. In a wrench such as described, a handle member, a rotatable head carried by said handle member, said handle member having radial notches formed therein, a detent member carried by the head and movable to engage said notches, said detent member having a projection thereon provided with two parallel faces adapted when the detent is in one position to engagethe sides of the notches and when said detent member is in the position opposite thereto to extend at right angles to the said notches, said projection having a second pair of faces extending at right angles to the parallel faces, said second mentioned faces being disposed in angular planes, said second mentioned faces terminatingshort of the first mentioned faces producing shoulders adapted to engage the wrench handle upon opposite sides of the notches when the projection is disposed at right angles to the notches, means for forcing said detent member in the direction of the notches of the handle, and means whereby said detent member can be operated. I

4. In a wrench such as described, a bandle member, said handle member having radial notches formed therein, a head having a socket formed therein, a detent member rotatable and slidable in said socket, said detent member comprising a cylindrical body portion having a milled periphery projecting through said head member, a sleeve extending from one side of said body portion of the detent member and a boss, having angularly disposed end surfaces, projecting from said body portion, upon the side opposite to the sleeve,gfor engagement with the notches in the handle member, and a spring IIItQPPOSGClIbGtWBGIl the detent member and body portion and disposed within the sleeve.

In testimony whereof I have hereunto aflixed my signature in the presence of the two subscribing witnesses.
